Question 2:

Code:

int f(int x)
{
    int d = x + 3;
    return(d);
}

Solution:

int f(int x)
{
    return(x + 3);
}

Comment:
Although in this case it's obvious that 'd' is not used later, it's still worth simplifying this and avoiding the unnecessary and meaningless temporary variable. In general, in any place in C in which you can use a variable name to mean its value, you can use a more complex expression instead if useful (and this is true of almost all programming languages).
